Multi-Protocol Labeled Switching (MPLS) labels must not be exchanged between the enclaves edge routers and any external neighbor routers.
MPLS label exchange via Label Distribution Protocol (LDP) or Resource Reservation Protocol (RSVP) with any external neighbor creates the risk of label spoofing that could disrupt optimum routing, o...Rule Medium Severity -
NET2002
Group -
Label Distribution Protocol (LDP) must be synchronized with the Interior Gateway Protocol (IGP) to minimize packet loss when an IGP adjacency is established prior to LDP peers completing label exchange.
Packet loss can occur when an IGP adjacency is established and the router begins forwarding packets using the new adjacency before the LDP label exchange completes between the peers on that link. P...Rule Low Severity -

Group -
Rapid Spanning Tree Protocol (STP) must be implemented at the access and distribution layers where Virtual Local Area Networks (VLANs) span multiple switches.
Spanning Tree Protocol (STP) is implemented on bridges and switches to prevent Layer 2 loops when a broadcast domain spans multiple bridges and switches and when redundant links are provisioned to ...Rule Low Severity -

Group -
A Quality of Service (QoS) policy must be implemented to provide preferred treatment for Command and Control (C2) real-time services and control plane traffic.
Different applications have unique requirements and toleration levels for delay, jitter, packet loss, and availability. To manage the multitude of applications and services, a network requires a Qu...Rule Low Severity -

Group -
Protocol Independent Multicast (PIM) must be disabled on all router interfaces that are not required to support multicast routing.
PIM is a routing protocol that is used by the IP core for forwarding multicast traffic. PIM operates independent of any particular IP routing protocol but makes use of the IP unicast routing table-...Rule Medium Severity

The content of the drawer really is up to you. It could have form fields, definition lists, text lists, labels, charts, progress bars, etc. Spacing recommendation is 24px margins. You can put tabs in here, and can also make the drawer scrollable.
